Definitions

  • the invention relates to the field of fire-resistant glazing. It relates to a fire-resistant glazing with a transparent fire protection layer arranged between two transparent carriers (eg glass panes).
  • fire protection layer In a fire-resistant glazing with between transparent supports (especially glass panes) arranged fire protection layer shatters the fire-facing side of the glass and it uses in case of fire, a foaming and / or haze of the fire protection layer.
  • the fire protection layer then acts cooling and / or insulating or reflective.
  • This fire protection layer can be constructed, for example, on the basis of silicates or based on hydrogels. Both have their advantages and disadvantages.
  • a fire-retardant glazing based on hydrogels is, for example, in DE 2713849 described in which a space between at least two parallel glass panes is filled with a gel.
  • the gel is formed in the polymerization of methacrylamide and acrylamide, wherein the polymerization with the aid of peroxides or persalts with the addition of an accelerating agent (eg diethylaminopropionitrile) and optionally a crosslinking agent (eg Methylenbisacrylamid, MBA) takes place.
  • an accelerating agent eg diethylaminopropionitrile
  • a crosslinking agent eg Methylenbisacrylamid, MBA
  • DE 10237395 describes a method of making a fire-resistant glazing wherein a fire-resistant composition is formed between two adjacent glass sheets.
  • the fire-resistant composition is formed by the polymerization of acrylic acid and / or methacrylic acid and / or their respective alkali salts and / or ammonium salts of acrylic acid, additionally using a salt solution, a polymerization initiator and a crosslinking agent, with basic salt solutions being indicated as preferred.
  • hydrogels are partially composed of toxic or carcinogenic or mutagenic raw materials (eg based on acrylamide / DE 2713849 ) or raw materials (water-soluble monomers) are used, which preferentially polymerize in the alkaline.
  • high pH values can cause unwanted reactions with glass surfaces (glass corrosion) and thus lead to turbidity.
  • Another disadvantage of the hydrogels used hitherto is their poor adhesion to the glass surface. In particular, by hydrolysis reactions by high pH values are chemical bonds to the glass surface either destroyed or do not even come off.
  • Hydrogels are also known which are produced on the basis of methylolacrylamide.
  • Methylolacrylamide can be prepared, for example, from the starting materials acrylamide and formaldehyde, both starting materials being harmful substances. They have been classified as SVHC (Substance of Very High Concern). SVHCs are chemical compounds (or part of a group of chemical compounds) that have been identified under the REACH Regulation (Registration, Evaluation, Authorization and Restriction of Chemicals) as having particularly hazardous properties. Therefore, acrylamide is also referred to as arcinogenic and mutagenic and formaldehyde is classified as toxic and presumed carcinogenic.
  • the fire-resistant glazing has at least two transparent carriers, between which a transparent layer of a fire protection layer is arranged.
  • the fire protection layer has a hydrogel. This has a polymer polymerized from at least one water-soluble, non-toxic monofunctional monomer and at least one bi- or polyfunctional monomer in an acidic medium (pH ⁇ 7) in an aqueous salt solution or in an aqueous salt dispersion.
  • glass panes in particular flat panes of glass, are suitable as transparent carriers.
  • ceramic glasses can be used and find special bent glasses application. Particularly favorable may be thermally or possibly chemically tempered glass panes.
  • Silicon oxide-based glass panes are also suitable for transparent polymer-based supports (for example made of polycarbonates or poly-methyl methacrylate (PMMA), partially crystalline "glasses" (ceramic glasses) or composite systems with glass panes and plastic carriers.
  • fire-resistant glazing is therefore to be understood as being functional and not limited to specific materials (specifically: glass in the narrower sense), but also expressly including structures with transparent or translucent supports of the abovementioned and other materials.
  • a hydrogel is a water-containing but water-insoluble (but water-compatible) polymer whose monomers are linked to a three-dimensional network.
  • An acidic solution has a pH ⁇ 7.
  • the hydrogel is polymerized in a solution having a pH of less than 6.5, for example a pH of at most 6 or, for example, at a pH of at most 4.7.
  • a non-toxic monomer is a chemical compound that does not fall into the "Acute Toxicity" hazard class under the United Nations Globally Harmonized System of Classification, Labeling and Chemicals (GHS) Hazard designation toxic (code letter: T) or very toxic (code letter: T +).
  • GHS Globally Harmonized System of Classification, Labeling and Chemicals
  • the said monofunctional and, for example, bi- or polyfunctional monomers of the fire protection layer are not classified as carcinogenic (carcinogenic) and / or mutagenic (genotoxic).
  • the fire protection layer is not toxic both before the conversion to a hydrogel (starting materials) and ready-reacted hydrogel. This has the advantage that even in case of fire, the formation of toxic compounds is reduced. This is both a worker involved in making the fire-retardant layer and a person better protected against poisoning in the event of fire or breakage of the fire-resistant panes during use.
  • the polymerized fire protection layer forms a polar surface.
  • the polarity of the fire protection layer is influenced by the polarity of the ligands in the polymer chain.
  • This polar surface can interact efficiently with the surface of the glass sheet, greatly improving the adhesion of the fire protection layer to the glass sheet.
  • the improved adhesion can be particularly important in case of fire of great importance, since the fire protection layer remains connected after a cracking or bursting of the fire-side glass with the other glass and does not simply fall into the fire room (which would correspond to a total failure of the fire-resistant glazing). This improved adhesion is already achieved without the use of additional adhesion promoters.
  • a further advantage of a fire protection layer with a pH ⁇ 7 is that in the acidic environment the glass pane which comes into contact with the fire protection layer is attacked less strongly compared to the prior art, since so-called glass corrosion in acid is less pronounced than takes place in the alkaline. As a result, aging-related turbidity of the glass / glass pane is prevented.
  • the bifunctional monomer for example, methylenebisacrylamide (MBA) can be used.
  • MBA methylenebisacrylamide
  • the bi- or polyfunctional monomer causes or accelerates a three-dimensional crosslinking of the fire protection layer. This makes it possible that the fire protection layer after the polymerization no longer is fluid. Therefore, the dimensional stability of the fire protection layer and thus the fire-resistant glazing is significantly improved.
  • the initiation of the polymerization can be promoted by an initiator.
  • the initiator may be, for example, a water-soluble UV initiator of UV radical chain polymerization (after irradiation with ultraviolet radiation).
  • the initiator (or generally the polymerization) is thermally activated.
  • This makes it possible that only one initiator for initiating the polymerization of the fire protection layer is needed.
  • initiators are known which act as a redox system and have at least two reactants.
  • the use of less starting materials / starting materials (educts) for the fire protection layer makes it easier to homogenize the starting materials, which improves the efficiency of the polymerization and thus the quality of the fire-resistant glazing.
  • the thermal activation preferably starts above room temperature (the standard room temperature is defined as 23 ° C). This makes it possible that, when the starting materials (including the initiator) are homogenized, no polymerization takes place at room temperature. Therefore, no diligence is required in the careful production of the fire-resistant glazing, which reduces the susceptibility to errors and allows additional flexibility in the production process.
  • the fire protection compound which forms the fire protection layer after polymerizing is thus particularly preferably designed so that substantially no polymerization takes place at room temperature.
  • substantially no polymerization may mean, for example, that the viscosity of the hydrogel does not reach or exceed a value of 200 mPa s within 12 hours. In other words, the educts of Fire protection layer does not cure within an acceptable period of time (about 12 hours) without undergoing thermal activation.
  • the activation temperature for initiating the polymerization is below 100 ° C.
  • the polymerization starts at a temperature of 40 ° C to 75 ° C.
  • the activation temperature may be, for example, the lowest temperature at which the viscosity of the freshly mixed mass increases by a factor of 1000 within 1 to 2 hours, ie a viscosity of 400 mPas is reached. With a viscosity of 400 mPa s and more, the fire protection compound can not or hardly process and can then almost no longer flow.
  • a persalt can be used, in particular, peroxydisulfates are well suited for initiating the polymerization.
  • Persalts are the salts of a peracid, the term peracid being a collective term. Peracid is understood as meaning both oxoacids of higher oxygen content and peroxyacids (as well as peroxycarboxylic acids.)
  • Persalts are strong oxidizing agents which can initiate the radical reaction of the educts of the hydrogel into a polymer in a redox system with a reducing agent.
  • a further significant advantage is that the activation can take place in a targeted manner when the educts of the fire protection layer are at their destination, for example, between the at least two glass panes. This allows the processing such as mixing and homogenization of the reactants and the filling of the educts between the at least two glass sheets are carried out with great care and without haste. Therefore, the quality of fire-resistant glazing can be reproducibly secured at a high level.
  • the at least two glass panes of the fire-resistant glazing on the side facing the fire protection layer have a layer of organofunctional silane.
  • the organofunctional silane can be applied, for example, by spraying, roller application or by wiping on the glass pane.
  • the organofunctional silane may also be referred to as a functionalized silane.
  • the layer of organofunctional silane is a monomolecular layer.
  • This can be realized by means of a highly dilute solution of the functionalized silane in a volatile solvent, such as propanol or isopropanol, or a propanol-water mixture.
  • a volatile solvent such as propanol or isopropanol, or a propanol-water mixture.
  • the organofunctional silane can covalently bond with the fire protection layer.
  • Such a covalent bond in contrast to purely polar interactions can only be broken by a large amount of energy.
  • the fire protection layer adheres particularly well to the coated glass pane.
  • a lot of heat energy is available, whereby on the one hand, the covalent bonds between the fire protection layer and the functionalized silane are refracted on the side facing the fire and can solve the possible flaking glass from the fire protection layer.
  • the bond between fire protection layer and the functionalized silane remain on the side facing away from the fire, whereby the heat insulation of the fire-resistant glazing is maintained.
  • the initiated polymerization can not only take place within the fire protection layer, but can also spread to the functionalized silane.
  • a functionalized silane having at least one double bond may be, for example, a vinylsilane.
  • the water-soluble, non-toxic monomers from which the fire-resistant layer is reacted have in a group of embodiments at least acrylic acid or an acrylic acid derivative and methacrylamide or a derivative of the methacrylamide.
  • the fire protection layer before the reaction may have a content of 5-20% by weight of monomers.
  • a good three-dimensional crosslinking can be ensured, whereby the dimensional stability of the fire protection layer is significantly improved.
  • the proportion of the monomers may also be between 7 and 15% by weight of the fire protection layer before a reaction, wherein the crosslinking is particularly good. It is advantageous that the monomers have both acrylic acid or an acrylic acid derivative and also methacrylamide or a derivative of methacrylamide. This makes it possible to improve the three-dimensional crosslinking of the fire protection layer.
  • the proportion of acrylic acid and / or acrylic acid derivative plus methacrylamide and / or a methacrylamide derivative it should be between 5 and 20% (in each case in percentages by weight), preferably between 7 and 15%, particularly preferably between 8 and 12%. lies.
  • the ratio between methacrylamide and / or a methacrylamide derivative on the one hand and acrylic acid and / or acrylic acid derivative on the other hand is preferably between 0.5 and 2.5, in particular between 0.8 and 1.5, particularly preferably between 1 and 1.2.
  • the fire protection layer may also have a pH of less than 7 after the polymerization. This assists adhesion to the glass due to polar interactions. To improve the adhesion, it is not absolutely necessary to use a layer of organofunctional silane on the side facing the fire protection layer. In basic (pH> 7), the bonds between the fire protection layer and any layer of functionalized silane may be degenerated, which reduces the adhesion to the glass pane in the basic. In addition, in the acid (pH ⁇ 7), as mentioned, the so-called glass corrosion is reduced, whereby the fire-resistant glazing shows a greater resistance to aging.
  • the container may be formed by the first transparent support and additionally a second transparent support (eg likewise a glass pane) with a circumferential edge seal, wherein the edge seal is interrupted at at least one point in order to form a filling opening. After filling, the edge seal is then supplemented so that the filling opening is closed.
  • a filling step is (for a fire protection compound other than in the inventive process), for example in WO 03/031173 taught.
  • the first transparent support (glass or similar) can be stored horizontally with a peripheral edge boundary, so that the container is formed and filled in the manner of a trough by support and edge boundary.
  • the fire protection compound can then be cured and, if appropriate, also dried, whereupon a second transparent support is placed thereon and, if required, an edge seal is applied (the edge seal can also be formed at least partially by the boundary, which then remains on the first support).
  • attach the second carrier before or during curing. This process can be carried out, for example, under protective gas, so that no atmospheric oxygen can hinder the polymerization.
  • This procedure makes it possible for the polymerization to be started in a controlled manner only when the educts of the fire protection layer have been homogenized and in contact with at least the first carrier. This allows the steps in the manufacture of fire-resistant glazing be carried out with great care, whereby the reproducibility of the quality can be ensured.
  • the controlled start of the polymerization can be initiated by heating the fire protection layer. This ensures a homogeneous polymerization of the fire protection layer, for example in the space between the at least two glass panes.
  • the temperature must, as already mentioned, not be too high, so that a blistering in the fire protection layer is prevented.
  • One possible additional step concerns embodiments in which the carrier is formed as a glass sheet (tempered or non-tempered or laminated glass).
  • a layer of organofunctional silane can be applied to the glass pane or at least one of the glass panes on the side facing the fire protection layer.
  • the adhesion of the fire protection layer to the glass pane can be enhanced, which improves the fire protection properties of the fire protection glazing.
  • the procedure according to the invention can be applied not only to fire-resistant glazings with two transparent carriers and a fire protection layer therebetween, but also to any structures with transparent carriers and fire protection layer, in particular also structures with more than two carriers and more than one fire protection layer.
  • the pH of this acidic mixture is about 4.5. Subsequently, the mixture in the space, which is separated by the edge seal between two glass panes, filled. During a period of 400 minutes in an oven at 60 ° C, a polymerization is initiated and the fire protection layer cures between the two glass sheets.
  • the composite filled with the fire protection layer is heated at 55 ° C for 500 minutes in an oven.
  • the polymerization of the educts of the hydrogel is initiated by the heating and the fire protection layer cures in the space between the panes.
